Major Upgrades Completed on CJ's 2015 Mustang EcoBoost!

We've only had our 2015 Mustang EcoBoost for a few weeks, but we've already completed a massive amount of upgrades. Today, we're going to update you on where we're at and what we've got coming up for this all-new model.

COBB Accessport V3 Tuner

One of the easiest changes any owner can make to their 2015 Mustang EcoBoost is a new tune. We quickly learned that this upgrade can also be one of the most beneficial. To start, we needed to burn off all of the 87-octane fuel that came from the dealer, which entailed a weekend of driving, so we could fill it up with a tank of the 93-octane fuel that would be required for our tune.

After that, we headed to a local dyno shop and got a baseline reading for our Mustang EcoBoost with the factory tune. With this particular dyno, we saw 228 horsepower and 277 ft./lb. of torque from the factory. After that, we loaded the Stage 1 tune from our COBB Accessport V3 Tuner onto the car and, wow, were we impressed with the results!

We picked up 32 horsepower and 70 ft./lbs. of torque at the wheels!

With no modifications done to the car, we were thoroughly blown away at the gains. When Bill jumped behind the wheel, he said the additional power was noticeable, too. Watch the video below to see the process, and more of Bill's thoughts on this tune.

Now it's time to get to work on some modifications.

Airaid MXP Series Cold Air Intake Kit

As is the case for many Mustang owners, our first physical upgrade is a cold air intake. By allowing air to flow into your engine much better, these popular products offer more power and performance and a better sound, plus they just look amazing under the hood. On previous projects, we'd had lots of success with Airaid products, so we thought the Airaid MXP Series Cold Air Intake Kit would be a perfect upgrade for our Mustang EcoBoost.

While we have tuned our car, one of the benefits of this product is that it does not require a tune for the best performance. The kit also includes everything you need for the installation, making it easy for any skill level to install.

On the video below, Bill walks you through the installation process step-by-step. Make sure you stick around for the end, where you can hear the beautiful sound from our new Airaid intake.

MRT Turbo-Back Exhaust

From the moment the EcoBoost four cylinder was announced, owners have worried that the car would sound like a typical four cylinder and lose the Mustang's signature aggressive rumble. In order to calm these fears, Ford silenced the exhaust note on the Mustang EcoBoost as much as possible, and piped in a more aggressive tone through the car's speakers. For many, this isn't the fix they were looking for, and it doesn't really do anything about the typical weak performance that comes from every Ford factory exhaust.

While the aftermarket is never going to be able to get the deep rumble of a V8 exhaust out of a four cylinder, they can certainly make any Mustang EcoBoost product sound louder, deeper and more aggressive, plus allow it to perform much better. MRT has jumped in and created a high flow catted exhaust system for the Ford Mustang EcoBoost that significantly helps to address some of the sound issues.

Our Mustang EcoBoost now has a very aggressive tone that was absent with the factory exhaust. Performance is surely improved, thanks to the high flow characteristics of the new system, making us very happy with our new exhaust system.

If you're looking for even better performance than the catted version offers, and you don't care about being emissions-legal, MRT also offers an off-road version. The MRT Stainless Steel 3-inch to 2-1/2-inch Off-Road Turbo-Back Exhaust System with 4-inch Tips is pretty much the ultimate in performance and loudness for the Mustang EcoBoost. Bill also shows that installation in another video, though it is quite similar to the process for the catted version. However, the sound clips at the end show a significantly louder sound.

Eibach Sportline Lowering Springs

Last week, we installed a set of Niche Vicenza wheels onto our 2015 Mustang EcoBoost. By themselves, they look incredible, but we couldn't bring ourselves to share them with you, since your immediate feedback would be, "Lower that car!"

Well, we just lowered it. We went with the Eibach Sportline Spring Kit, which is the more aggressive of the two Eibach kits we offer, since we felt that the Mustang EcoBoost actually sat a bit higher than a GT, so we wanted to drop it a bit more than we would on a GT.

The installation only took a few hours and, as you'll see in the video, the results were dramatic. Combined with the new Niche wheels, we're loving the new look of our 2015 Mustang EcoBoost! As always, Bill walks you through the process step-by-step, giving you the assurance that this a project that you can complete, no matter your skill level.

Next Steps

Our 2015 Ford Mustang EcoBoost is a true test car for us, so you're going to see many more new cold air intakes, exhaust systems and even adjustable coilovers getting installed in the not too distant future. As soon as new 2015 Mustang products hit the market, we're going to get them, show you how they work and how you can install them on your Mustang.
